BRUSH HAVING A NAIN BRUSH AND A FLEXIBLY MOUNTED ROLL IN ADVANCE OF SAIDMAIN BRUSH Filed June 13, 1957 ATTORNEY Unite States Patent Oce BRUSHHAVING A MAIN BRUSH AND A FLEX- IBLY MOUNTED ROLL 'IN ADVANCE 0F SAIDMAIN BRUSH y Peter S. Vosbikian and Thomas S. Vosbikiau, both ofMelrose, Pa.

Filed June 13, 1957, Ser. No. 665,481 4 claims. (ci. 15-118) The objectof our present invention is to devise a novel brush having a novel,replaceable applicator of suitable absorbent characteristics which isassembled with a exible and resilient spring member of metal, plastic orother suitable material, the applicator and the spring member beingdetachably connected with a brush head. The spring member may bepermanently fixed to the handle or removably connected therewith, andthe applicator may be permanently xed to the spring memberor removablyconnected with it. j e

Sincerthe applicator can be manufactured at a cost of a few cents, itcan, when it becomes worn or clogged with paint or other material beingapplied, be discarded, and a new applicator applied to the springmember, or the applicator and spring member can be discarded for newones.

A further object is to provide a novel constructionand arrangement of anadditional applicator in the form of a roll of absorbent material whichwill retain the treating material and can be simultaneously with themain applicator applied to a surface to be treated, said additionalapplicator having a novel mounting and locking arrangement whereby itcan be removed when desired.

With the foregoing and other objects in view as will hereinafter clearlyappear, our invention comprehends a novel brush having a removableapplicator tensioned in a novel manner and having its tension caused bya spring member connected with it and with a handle.

For the purpose of illustrating the invention, we have shown in theaccompanying drawings preferred embodiments of it which we have found,in practice, to give satisfactory and reliable results. It is, however,to be understood that the various instrumentalities of which theinvention consists can be variously arranged and organized and theinvention is not limited, except by the scope of the appended claims, tothe exact arrangement and organization of these instrumentalities asherein shown.

Referring to the drawings:

1 designates a brush embodying our invention as shown in Figures l to 3inclusive, the brush being provided with a handle 2 to which a clampingplate 3 having upstanding sides 4 is secured by a clamping plate 5 and afastening device 6 of any desired character.

An applicator 7 consisting kof a block of absorbent material, forexample a cellular plastic, has a spring member 8 inserted into it fromits -rear end and is preferably glued on both sides to abutting portionsof the applicator. This spring member may be formed in many differentways but as shown is in the form of a flexible and resilient springplate having a clearance with the sides and front end of the applicator.The spring member .8 may be of spring metal, plastic or of any othersuitable spring material. n

The applicator is cut into -to Vform a slit open at only the rear end ofthe applicator. V-

The front end of the handle 2 is preferably recessed on its top andbottom faces to receive the clamping members 3 and 5 which at theirfront ends converge towards'each other as at 9 and define the flexingline of the applicator.

The spring member 8 is apertured to receive the bolt of the fasteningdevice and abuts against the frontend of the handle and the rear portionof the applicator 'is compressed between the clamping plates 3 and 5. .l

In Figures l to 3, the applicator is shownv as a block of materialhaving a slit opening through its rear end to receive the spring member,and in Figure 4, the applicator consists of two strips 10 and llrbetweenwhich a spring member 12 is secured by suitable adhesive 'or glue toform a unit of'structure. l

Inthe embodiment seen inAFigures 5 to y8, inclusive, a handle13 has anenlarged front end- 14 secured by fastening devices 15 to a clampingplate 16, and an applicator 17 has a spring member 18 extending into it.The slit in the applicator 17 is closed at the front and at oppositesides so that the sides and front of the spring 18 are spaced from thesides and front of the applicator. 'Ihe clamping means in Figs. 1, 2, 5and 7 secure the rear ends of both the spring and applicator to thehandle. A clamping plate 19 is clamped to the plate 16 by a fasteningdevice 20 which passes through an aperture in the spring member 18. Theconstruction thus far described in Figure 5 is substantially the same ascorresponding parts of Figure l. In Figures 5 to 8, an additionalapplicator is provided. A mounting rod 20 has a lateral stretch at itsforward end on which a roll 21 of absorbent material is free to revolve,the roll being retained on said lateral stretch by a fastening device 22of any desired construction. The rod 20 extends rearwardly along a sideof the applicator and is deflected inwardly and then rearwardly toterminate in a laterally extending prong 23 received in an aperture inthe handle. A locking sleeve 24 slidable on the handle locks the rod toor releases it from the handle. One of the clamping plates 16 or 19 andas shown the clamping plate 16 has a side ange deflected to form agroove 25 into which the rod 20 snaps to maintain the roll 21 in advanceof and in longitudinal alignment with the applicator 17.

In the embodiments seen in Figs. 1 and 5, the spring Y member forms aunit of structure with the applicator, while in Figure 9 we have shownthe spring member fixed to the handle and the applicator replaceable.The spring member 26 is driveninto a slit 27 in the handle 28. Theclamping plates 29 and 30 clamp the applicator 32 to the spring memberand to the handle. The applicator 32 has a slit 33 to receive the springmember which latter is apertured to receive the bolt of the fasteningdevice 31. The forward end of the applicator may have any desired shapebeing shown converging in Figure 9 and rounded in Figures l, 5 and 7.

The applicators 7, 17 and 32 are shown as substantially rectangular incontour with flat sides but they may have any other desired contour inaccordance with the Work Patented July 26,1960` which they are toaccomplish. The applicators take the place of the conventional bristlesand have the advantages that they do not drip and will carry a largeamount of liquid, semi-paste or paste-like material being usedto coat asurface.

Particular attentionn is directed to the novel spring member preferablyembedded in the applicator andY its mounting which defines abending lineat the front of the clamping plates, so that' during painting or similaroperations with a side contacting theV work a flexible pressure isapplied to about one-half ofthe applicator to feed the material theretothe surface to be treated.

When the roll is used, the coating material is sirnultaneously smoothedout by a side face of the mainapplicator when the handle is inclined atless than a right angle to the plane of the surface to be treated.

When the handle is inclined to the work, the rear portion of thelongitudinal stretch of the rod 20 is in the groove 25 of clamping plate19, so that the portion of the rod in advance of the clamping plate isfree to bend and both the applicator and roll will contact the surfacebeing treated. If abnormal pressure is applied to the handle when in aninclined position, the rod can move out of the groove and the rod isfree to bend adjacent the sleeve 24.

It will further be apparent that the roll can be quickly removed withoutthe aid of tools when only the main applicator is to be used.

Having thus described our invention, what we claim as new and desire tosecure by Letters Patent is:

l. A brush comprising an applicator in the form of a substantiallyrectangular block of absorbent, resilient material having a slit spacedfrom itsfront and opening through its rear end, a flat, exible springsubstantially lling said slit with its front and side edgesspaced fromthe front and side walls of the applicator, a handle, means to securethe applicator and spring to the handle, a roll mounting rod having itsinner end detachably connected with the handle and having a stretchextending along a side of the applicator and terminating in a lateralstretch in front of the applicator, and an absorbent roll mounted on thelateral stretch.

2'. The construction defined in claim l, wherein side walls of the slitare closed.

3. The construction defined in claim l, wherein the handle has anaperture, the rod has a deected portion to be received in said aperture,and a sleeve slidable on the handle and over the rod locks the inner endof the rod to the handle.

4. The construction delined in claim l, 'wherein the means for securingthe applicator and spring to the handle includes a clamping deviceextending over only the rear portions of the applicator and spring andhas a side groove to receive the mounting rod and retain it in assemblywithv the applicator.
